Figure 5.
Example of a 36-year-old female patient with recurrent CCA in the left liver lobe after right hemihepatectomy and systemic chemotherapy (gemcitabine/cisplatin), not detected on CT and MRI. Recurrence was suspected clinically by elevated tumor markers (CA 19.9). Before PET/CT, clinicians intended further imaging and biopsy to prove suspected recurrence, and revised their “non-treatment” strategy into a “palliative treatment” goal (with change of chemotherapy regimen) after PET/CT (major change).
